Title: Method
for Inductive Charging of a Headset Battery Using the Speaker Coil

This concept relates to power
transmission; specifically inductive power coupling with no exposed electrical
contacts.

Description of the problem this invention
solves:

Any rechargeable battery powered
device typically has to allow a method by which to connect and deliver the
power to a discharged battery. This
often requires specific mechanical connectors or interfaces that will complete
the electrical circuit to allow power transmission to charge the battery. These connectors are often complex or
unsightly due to the need to design a contact method that is durable and
protects a user from exposure to any electrical contacts or interface during
device usage and/or periods of device battery charging. This concept would allow device battery
recharging without the need to complete any direct electrical connection
between the device (headset or handset) and its power adapter or base station.

Previous Solutionsfor the Problem

There are numerous prior solutions or
solution attempts that address power connection for battery charging. There are specific prior solutions which
even utilize an inductive charging method as described here. The uniqueness of this concept is to
leverage the design of a headset speaker, which already contains a wound conductive
coil, to transfer power to a battery charge circuit in the headset.
